HiDIYous

Its a Diy HID Implant that you can implant in whatever! With a size of 10x11mm (The PCB Manufacturer cant do anything smaller than 10x10, but it is possible to reduce to 10x7mm but that is an excercise for the reader)

HiDIYous

Howto

  • Installed Arduino IDE
  • ArduinoUNO or ISP Programmer
    • Jumper cables x6
    • 10uF Capacitor
    • (optional) SOIC-8 Clip
  • USB Breakout cable, either Buy or DIY (I went with the DIY route)
  • Installed avrdude

Hardware

Based around ATTiny85 and DigiKeyboard library, Designed in EasyEDA.

Order a assembled PCB from JLCPCB.com

  • TODO Gerber file: hardware/Gerber.zip
  • Bill Of Materials: hardware/BOM.csv
  • Pick and Place: hardware/PP.csv

Pick preferred color, and PCB Thickness (Recommended 1.0mm)

ArduinoUNO

Insert your Arduino UNO into the computer, and upload the sketch ISP Programmer found under examples.
ArduinoISP: File > Examples > 11.ArduinoISP > ArduinoISP
Compile and Upload to the UNO

Docs: ArduinoISP

ISP Programming Pinout:

Flash Bootloader

This example is using an ArduinoUNO as a ISP programmer, YMMV with other hardware.

# Setting the correct fuses for bootloader burnin
avrdude -c arduino -p attiny85 -P /dev/ttyACM1 -b 19200 -Uflash:w:"software/bootloader.hex":i -U lfuse:w:0xe1:m -U hfuse:w:0xdd:m -U efuse:w:0xfe:m

Arduino IDE PCB Setup

Add the following url to the Arduino IDEs additional boards url https://raw.githubusercontent.com/digistump/arduino-boards-index/master/package_digistump_index.json

Then go to Tools > Board > Boards manager
Search for Digispark and install the package: Digistump AVR Boards

Replace micronucleus for Arduino IDE

The digistump library is shipped with a faulty micronucleus binary for v2.3 bootloader, a working binary is included in this repo software/micronucleus

Locate the arduino packages folder and browse to ~/.arduino15/packages/digistump/tools/micronucleus/2.0a4/micronucleus Replace the micronucleus with the included binary

Upload code

Open the file software/inject.example.ino into the Arduino IDE, and select the board configuration Tools > Board > Digistump AVR Boards > Digispark Default (16.5MHz).

Upload the code with the regular Arduino IDE workflow

Setup the pinout according to the chip silkscreen

Now you are finished and are ready to implant it into whatever USB Peripheral you want.
